MACHINE FOR MAKING BOOK-COVERS.V

Specification forming part of Letters Patent No. 46,353, dated February14, 1865.

.To all whom it may concern.-

Beit known that 1, JAMES W. HARRISON, of the city and county ofWashington, in the District of Columbia, have invented a new and usefulMachine for Making Cases in Book- Binding; and the following is a full,clear, and exact description ofthe same, reference being had to theaccompanying drawings, makinga part of this specification. inwhichlFigure 1 represents a front view ofthe machine. Fig. 2 shows a topview of the same, the adjustable gage, and folding wings. Fig. 3 is asection through the gage, showing the apparatus for holding and placingthe back linings in the cases. Fig. 4 is a detached view of one of thefolding wings C, showing the device for adjusting its length.

The object of my invention is to save time and labor in the process ofputting togetherl the several parts ot' which book-covers are composed,technically termed making cases.

My invention consists in the construction of the gage, the same being soarranged and operated as to hold a quantity of the back linings in thegage and place them one at a time automatically in the cases in the mostperfect manner, also in the arrangement and combination of theadjustable automatic folding wings, the same being operated by footpedals, levers, or cams in such a manner as to leave the hands of theworkman free to place the material in position and remove the casesformed without coming in contact with the glue or mucilage.

To enabled others skilled in the art to make and use my invention ormachinery for making cases or book-covers, I describe it morefully,referring to the drawings and to the letters marked thereon.

l make a table, A, of suitable dimensions, it

' being supported on legs or a strong frame in the usual manner. In thetop of the table A is fitted slides B B, which are made to beadjustedand are held firmly in any desired position by the thumb-screwsb b. On the top of the slides B B are placed two of the folding win gs DD. The apparatus for operating them consists ofthe segments ofgear-wheels d d, backsce, andle-versff, all ofwhich are secured to theslides B B, so that their operation is the same, to turn over the clothor other material with which the outside of t-he case is covered, whensecured in any position to favor the width of the case-the slides B Bbeing constructed so as to adjust the width of the cover or case fromboth sides of the center of the machine. At right angles with thefolding wings D D are placed similarly-constructed folding wings C C,operated in a similar manner, to turn over the top and bottom of thecloth on the case. These wings C C are made so' that they can beextended longitudinally to favor the width of the back of the case orbookcover. This is effected by having the folding parts of the wings g gparted in the center and made to slide on the hinge or center piece, h,and secured to it by set-screws s e, working in slotsw w. (See Fig. 4.)On the ex treme ends of the wings g g are nibs i' i, turned up at rightangles, for the purpose ot' indenting and forcing in the cover againstthe edge of the pasteboard right at the corners, so as to make smoothand even corners when the material is brought over by the other wings, CC, to complete the case.

For the purpose of placing the back linings centrally and truly on thecase without handling and at the same time have the gage in position toplace the pasteboards, I have the gage E, attached to a sliding post, F,which is placed centrally with the turning over or folding apparatus inthe rear of the table A,

so that the gage E is elevated and held up by a yielding spring, j,directly over the cover, so that when it is depressed by the action ot'-the foot on thepedal G, thelinings being in the gage, the bottom one isbrought in contact with the glue or mucilage on the cover, which adheresto it. The pasteboards, being then placed to the gage, it is allowed tobe raised by the action of the spring, leaving the back lining and thepasteboards in their places to be folded in.

The gage E is made of metal, the arms 7c 7c being of such width as toform a box, or reeeptaclevto contain a quantity ofthe linings, and aremade so as to be adjusted to any dcsired width of the back of the caseor bookcover. ends by resting on the ledges of slight springs m mi,which are attached to slitted bars n fn,

so that they can be moved and adjusted to' any desired point and thensecured by setscrews o o.

When the back of the cases are very wide, there may be a tendency of thelinings to The linings are supportedon theirsag and fall below thebottom of the gage, and draw the ends off' the narrow ledges of thesprings m m and fall on the case at atime and in numbers not wanted.This I prevent by having one or more very iinewires,p1),they having aslight enlargement at the lower end, the same passingup through smallpunetures i in the linings and secured in a suspended position to aslitted bar, q q, on the top. These suspended wires keep the linings ona level with the bottom of the gage, while they present no obstacle to asingle lining being drawn off when its lower surface comes in contactwith the glue. To operate, I adjust the gage to the desired width of theback of the cases and secure it by the set-screws. The linings, beingcut to the proper length and width, are placed in the gage, they beingsupported on the springs and thin vertical rods. The cloth for thecovers, being cut the proper dimensions, is placed upon a zinc plate,where the glue is spread over its surface. It is then placed centrallyon the machine under the gige, which is brought down upon lthe cloth nythe action of the foot on the center pedal, G, and held there, while-thetwo pasteboards are placed. The gage, being th en released from itspressure, resumes its elevated position,

lcavingthe back lil'lingfixed inits place. Then the left-foot pedal, H,is pressed down, which operates the foldil'ig-wings C C, and turns overthe cloth and secures it at the top and bottom ot' the case. The footisthen changed to the right pedal, I, which, being pressed down, in likemanner operates the foldingwings D D, thus turning over the other edgesand securing them, when the case is ready to be removed from the machineand rubbed down.

The whole process of making casessuch as feeding in the cloth in stripsfrom ofi' rollers, spreading the glue on the same, cutting the covers tothe size, placing them and the pasteboard on them,re1noving and rubbingdown `and completing the cases- I contemplate doing by machinery,operated automatically, and for which I purpose subsequently to makeapplication for separate patents.

Having described my invention, or such portions of it as are shown inthe accompanying drawings, what I claim as new, and desire to secure byLetters Patent, is 1. The gage, the same being so constructed as to forma box or receptacle to contain a quantity of back linings, and sooperated as to place them automatically, one at a time, in the case, atthe same time the gage is in its position for placing the pasteboards,as described, for the purposes herein set forth.

2. 1n combination With adjustable backy gage, the adjustable automaticfolding-wings, the same being operated by cams or footpedals, levers,and springs, for the purpose of turning over and securing the cloth onthe cases in making book-covers, as herein speciiied.
